About the IS200EAUXH1A

The IS200EAUXH1A model is part of the EX2100e systems, produced by General Electric Industrial Systems. The IS200EAUXH1A model is an Exciter Auxiliary Interface, which is the definition of the functional acronym EAUX. The printed wiring type for this board is an I/O Terminal Board. As part of the EX2100e system, this model can perform on advanced platforms for different types of generator excitation systems. This model differs from those in the standard EX2100 system as the “e” in the EX2100e indicates that any of the models within this system have enhanced technology. 

The IS200EAUXH1A model is used as a Digital Controller in Thyristor-based systems. The connection between the EAUX model and the main control processor is through the High-speed Serial Link (HSSL) board. This model also connects to the High-speed Serial Link Interface (HSLA) board for host applications, when these boards are connected the EAUX board will produce an output of 41 VDC. 

Model IS200EAUXH1A does not have a part-specific manual and has very little information on it, but information can be found in the GEA-S1302A EX2100e Excitation Control 100, 77, 53, and 42 mm Thyristor Systems Users Guide. 

The IS200EAUXH1A model is mostly obsolete at this point but is carried by AX Control. For pricing information reach out to our sales team so they can give you a price estimate. We also offer repairs and can give you repair estimates as well.
